To all whom it may concern: pass through keepers attached to the wings Be it known that I, LEWIS (3. ASHLEY, of H. \Vith this construction, when the force of Detroit, in the county of Wayne and State of the wind exceeds the resisting power of the lllichigan, have invented anew and useful Imsprings I, the said springs willyield and allow proveinent in WVindmills, of which the followthe wings H to turn upon their pivots, bring- 55 ing is a specification. ing their edges to the wind.
